LM1086CS-3.3/NOPB

Overview

The LM1086CS-3.3/NOPB is a fixed positive low-dropout linear regulator manufactured by Texas Instruments, delivering a stable 3.3V output with a maximum current capacity of 1.5A. It operates within an input voltage range up to 27V and features a typical dropout voltage of 1.3V at full load. The device is housed in a surface-mount D2PAK (TO-263-3) package, suitable for thermal-efficient designs. It supports an extended operating temperature range from -40°C to +125°C, ensuring reliable performance in demanding industrial environments.

Feature Summary

Provides a fixed 3.3V regulated output for power supply applications
Supports high-load currents up to 1.5A with low dropout characteristics
Integrated thermal overload and short-circuit protection mechanisms

Applications

Point-of-load regulation in embedded systems
Power conditioning for microcontroller units
Battery-powered equipment requiring efficient voltage step-down

Procurement Notes

Verify the complete part number including the suffix to ensure correct output voltage and package configuration. Confirm RoHS compliance status as indicated by the NOPB designation. Check datasheet revisions for any updates to electrical characteristics or recommended external component values before finalizing design integration.

Selection Notes

Select this component when a fixed 3.3V rail is required with moderate current demands. Ensure the input voltage remains within the specified maximum limit to prevent damage. Consider thermal management requirements due to power dissipation at higher load currents. Verify that the TO-263-3 package fits the available PCB footprint and thermal pad constraints.

Part Context

This device belongs to the LM1086 family of 1.5A low-dropout regulators. It shares functional similarities with other variants offering different fixed voltages or adjustable outputs. The CS suffix denotes commercial grade temperature range, while the TO-263 package provides robust heat dissipation capabilities compared to smaller SOT packages.
